GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,073, dated March14, 1882.

- Application filed October 7, 1881. (No model.)

To all whom it may concern Be it known that I, EDWARD G. BURGESS, of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented an Improvementin Gas-Machines, of which the following is aspecification.

My invention has reference to automatic gasgenerating machines; and itconsists of two pistons working in two cylinders, one of which is keptconstantly hot, said pistons being con nected together, one of which isadapted to pump hot air and the other adapted to be act uated byexpanding hydrocarbon vapor generated from oil; further, in devicescombined with the aforesaid pistons and an oil-pump operating to feed alimited quantity of oil to the hydrocarbon-cylinder, where it isvaporized; further, in providing a constant exhaust for hydrocarbonvapor from thehydrocarbon-cylinder into the gasmain, where it is mixedwith heated air, and in 'minor details of construction, all of which ismore fully set forth in the following specification, and shown in the accompanyingdrawingspvhich form partthereof.

Heretofore, so far as I am aware, adoubleactingblast-cylinder adapted topump hot air when combined with a hydrocarbon vapor gem erator having aconstant exhaust has never been used. Neither has the constant exhaustfor the hydrocarbon vapor to enablea constant mixing of the vapor withthe hot air been known previous to my invention thereof. These parts,when combined with suitable oilpumpingmechanism, an intermittenthydrocarbouvapor exhaust, a hot-air chamber inclosing thehydrocarbon-vapor generator, or a holder to prevent the pulsations ofthe pump affecting the light given by burning the gas taken from themains, arealso new.

Hydrocarbongenerators broadly are old, as

are also gas-machines which mix air with hydrocarbon vapor.Double-acting hot-blast cylinders,when arranged with ahydrocarbon-generator, have also been used. Therefore 1 do not claimthese features, broadly, but only in combination with other specificfeatures, as

set forth in the statement ofinvention and in the appended claims.

The objectof this invention is to produce an illuminant from oil andheated air and constructa machine for that purpose which shall beautomatic in its action.

In the drawings, Figure l is a sectional elevation of a gas-machineembodying in it my improvements. Fig. 2 is an enlarged detail view ofthe mechanism to actuate the pump to feed the oil to thegenerating-cylinder. Fig. 3 is a perspective view of the doubleratchetwheel in the device shown in Fig. 2.

A is the bed or base plate, and is provided with holes or apertures b,and carries at the top a plate, B, to which it is secured by bolts 0,and located between the two isa sheet-iron casing, D, which iuclosesthehydrocarbon-gasgenerating cylinder G.

Inclosing the casi'n g D is a wooden casing, F, and between the two isan annular space,

f, which is in communication at the top and bottom with the air byholesfin plates A and B. Secured to the plate B, and located within thecasing D, is the generating-cylinder G, which is made heavy atthebottom, as'shown, to retain heat, and provided with the oil-chamber g.

The piston I is provided with a valve, 6, through the same, and issecured on the bottom of a piston-rod, H, which passes through plate Band is secured to piston K, which works in the ail-cylinder J. Thepiston-rod H, or its rquivalent, H, extends up through thecylinder-head, and is secured to the crosshead P,-earrying rodspp,having racks Q Q. at the bottom. The air-cylinder is arranged to drawhot air from within the casingD through pipe L and pump it out throughpipes M into the main N, into which the hydrocarbon vapor also passesfrom cylinder Gr by means of pipes 11. and n, which are respectivelyfurnished with cocks or needle-valves O O. From the main N the mixedhydrocarbon vapor and hot air is forced into the gasometer or holder Xthrough the checkvalve o The holderX is a cylindrical vessel, providedwith a series of shelves, t, upon which'rest light valves 1. The gasfrom holderXpasses by pipey through the regulator Y to main Z. Thering-burner k is located immediately under the generator-cylinder G andwithin casing D, and is in communication with the gas-holder, fromwhence it receives its gas wherewith to heat the cylinder. The racks Qmesh with gear-wheels S on shaft 6.

The double ratchet-wheel R R carries the chain T, to one end of which isa weight, U, and to the other the pump-rod, which works in a'pump,V,which draws oil from a well by pipe W and forces it to the chamber g inthe genorator-cylinder G by pipe W.

The gear-wheel S is loose with reference to the ratchet-wheels, and inthe upward movement of the rack Q the pawl 1*, which is pivoted to thegear-wheel, rotates the ratchetwheels It and It, at the same timelifting up the weight U and lowering the pump-rod. When the weight isfully raised it is held in position by the pawl T, which is pivoted tothe frame A, catching the ratchet-wheel R, said pawlbeing pressed intocontact with the wheel by spring T The pump-rod and weight now remainstationary until the rod 12, carrying the collar or step q, descends,when the collar presses down the end of the arm of the pawl, throwing itout of contact with wheel It, when the weight U descends, raising thepump-rod and rotating the ratchet-wheels R R back to their originalposition.

The operation is as follows: The cylinder G being heated, thehydrocarbon vapor, expanding, closes the valve '5 and forces up thepiston I, said vapor constantly escaping with the exhaustnthroughneedle-valveO, and,after reaching its highest point, through the pipe nand valve 0 in the gas-main N. As the piston I ascends the piston K alsoascends and forces hot air into the main N, where it mixes with thehydrocarbon gas or vapor from pipes n and a. As the pistons ascend theweight U is raised and the pump-rod lowered, and as the pistons descendthe valve 43 opens to allow the vapor to pass through the piston and outthrough the pipe at to main N. Just as the bottom of the stroke isreached the collar q trips the pawl a", and the weight U comes into playand forces a small quantity of oil into the chamberg of thegenerator-cylinder G, and so on. The flame from the ring-burner 7c isfed with air by holes b, as is also the hot air from the cylinder J. Themixed hydrocarbon vapor and hot air in pipe N passes through acheckvalve, n into the gasometer or holder X, and rises from the bottomto the top through the valves t, which prevents the pulsations of thepiston K affecting the pressure of the gas in the main Z.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. 'In aygas-maohine, the combination ofthe cylinders G and J with their pistons I and K and piston-rods H H,cross-head P, rods p, carrying racks Q at their bottoms, ratchetwheels Rand It, pawls r and r, pinions S,
